Reactive Discovery of Point-to-Point Routes
in Low-Power and Lossy Networks
Abstract
This document specifies a point-to-point route discovery mechanism,
complementary to the Routing Protocol for Low-power and Lossy
Networks (RPL) core functionality. This mechanism allows an IPv6
router to discover "on demand" routes to one or more IPv6 routers in
a Low-power and Lossy Network (LLN) such that the discovered routes
meet specified metrics constraints.
Status of This Memo
This document is not an Internet Standards Track specification; it is
published for examination, experimental implementation, and
evaluation.
This document defines an Experimental Protocol for the Internet
community. This document is a product of the Internet Engineering
Task Force (IETF). It represents the consensus of the IETF
community. It has received public review and has been approved for
publication by the Internet Engineering Steering Group (IESG). Not
all documents approved by the IESG are a candidate for any level of
Internet Standard; see Section 2 of RFC 5741.
